However, when the hard drive was started on the fluid bearing, its motor parts were cold. The fluid inside the bearing still takes time to get the hard drive it needs to get the best performance. This is called warm-up time. During this warm-up, the platters on the hard drive vibrate vertically. These vibrations can cause read / to write errors. This is one of the reasons why hard drives fail.
This does not mean that it is always happening. However, vertical vibrations can damage the hard drive’s firmware and service area. The area with the highest vertical vibration is the outermost area of the disk. This area is also where the Hard Disk Service Track is located. Service Track is a system that starts up when the hard disk stops, so over time, the firmware in the Service Track is lost.
